IMPROVEMENT IN MACHINES FOR WINDING PAPER.

Specification forming part of Letters Patent No. 158,204, dated December 29, 1874; application filed November 24, 1874.

To all whom it may concern Be it known that I, BENJAMIN I EATON, of Albany, in the county of Albany and State of New York, have invented an Improvement in Winding and Cutting Paper, of which the following is a specification:

This invention is made for cutting up a wide web of paper as it runs from a roll, and winding it upon as many different shafts as there are separate rolls.

Heretofore difficulty has been experienced in so regulating the speed of the winding-rolls as to compensate for the increase of size of the roll of paper.

My improvement relates to a friction-belt for winding up the paper, and a yielding tightener. for such belt, operated by the roll of paper in such a manner that as the roll of paper increases in size the friction by the belt is proportionately lessened, thereby preventing the paper being torn by too great tension.

In the drawing, Figure 1 is a vertical section of the cutting and winding machine, and Fig. 2 is a plan of the same.

The roll of paper a is upon a shaft, to, that is set into the open jaw-bearings in the frame I) b, and a trap, c, and spring applied to the shaft 0, acts as a frictional detainer to prevent the roll turning from any inequality of weight at the sides of the shaft. The web of paper is led under the roller cl beneath and over the roller 6, so as to keep the paper out flat; thence it passes between the cutters or shears f and 9. These are made as disks set upon the respective shafts f and g, and these disks act in the well-known manner as rotary shears to divide up the paper whenever there are two of such shears placed to run in connection with each other.

Theweb of paper may be cut up into two or more strips of equal or unequal width, and these pass between the guide rollers or bars 70 k.

The winding-shafts l l are supported in the frame of the machine. There may be two or more, and each shaft should be made with a slip-socket and removable spindle, upon which the paper is wound, so as to facilitate the removal of the rolls of paper from the machine.

These winding-shafts are all connected by the pulleys and belt m, or by gearing, so as to travel at uniform speed, and the power is derived for moving these by the belt a from the driving-pulley 0 to the pulley r on one of the shafts, l or Z, and this belt a is loose, so that it may slip upon the pulley 0, except when its tension is increased by the spring tighteningpulley s, which is upon an arm, t, from the shaft to, and this shaft a has a springarm, w, that extends from it, and lies against the paper in one of the rolls.

As the rolls of paper increase uniformly the speed of rotation of the winding-shafts will have to be lessened alike in all. This is accomplished by the spring-arm to being pressed back by one of the rolls of paper, and relievin g the pressure of the spring tightening-roller 8 upon the belt n.v Such belt is allowed to slip more freely in proportion to the increase of size of the rolls of paper as wound.

I remark that the revolving shears and rollers should be driven at a uniform speed by connecting-belts 5 and 6 with pulleys on the driving-shaft.

I claim as my invention- The spring-arm w and tighteningpulley s B. F. EATON.
